Method for correcting the eccentricity of a vehicle wheel in balancing machines or the like

A method for correcting the eccentricity of a vehicle wheel in balancing machines, comprising:

• a reading phase for reading the radial eccentricity deviation of the rim of a wheel to be balanced and the radial eccentricity deviation of the tire of said wheel, read at a plurality of predetermined angular positions along the entire outer perimeter of said rim and of said tire;
• wherein the method comprises:
• a processing phase of the total radial eccentricity deviation values of said wheel, starting with said radial eccentricity deviations of the rim and of the tire read and according to the angular coupling positions between said rim and said tire;
• a definition phase for defining a geometric irregularity index of said wheel, determined according to the total radial eccentricity deviation values of said wheel and according to the angular coupling position between said rim and said tire;
• a determination phase for determining an optimal coupling angular position between said tire and said rim, selected among all the possible angular coupling positions, in which the value of said index is minimum;
• said index being calculated starting from the values of the harmonics relating to the total radial deviation of the wheel and determined accordingly to the mathematical function analysis method,
• said harmonics comprising the first harmonic or at least one harmonic of higher order.
